Aguilar is also facing charges of willful cruelty to a child, inflicting injury upon a child, two counts of assault with deadly weapon, assault by means of force likely to produce great bodily injury, and resisting an executive officer, according to court records.

Montclair police said Aguilar tried to kill her 8-year- old daughter on Oct. 31 by slamming their vehicle into the back of a tractor-trailer on the westbound 10 Freeway near Mills Avenue.

Witnesses then reported seeing Aguilar punch the girl and slam her head into the vehicle's center console, authorities said.

Passing motorists stopped and kept Aguilar away from the child until a California Highway Patrol officer arrived. Police said Aguilar also attacked the officer.

She was scheduled to be arraigned Monday, but since charges were only filed that afternoon, the hearing was postponed another day, court officials said.

Aguilar is expected to have a video arraignment today in West Valley Superior Court in Rancho Cucamonga.
